Marcylove , concerning your original 1st post question about the age of the painting of General Lee :
I'm very uncertain of the date of origin of your painting , however -
The image depicts Lee in a CSA uniform , with the three stars 'rank' of a colonel in the Confederate Army , which he had joined on April 23rd , 1861 .
Lee was appointed one of the first 5 generals in the CSA , but he continued to wear the three stars of a colonel for the duration of his service in the Confederate Army .
He personally indended to wear the rank of General on his uniform only after the war had ended .
Regarding the questions about conservation of your item(s) , I'd suggest you locate an art conservator in your area & take it to them for assessment (this is usually free) regarding work needed on each item .
Professional conservators work with standard rates (per square inch/centimeter) for the variety of services they provide & can quote you FIRM prices for their work .
They can & will photo-document disassembly & conservation of items (for a price) , so as to be able to verify exact condition before , during & after conservation work happens (it's great to have such documentation , with valuable artwork , to 'cut-off' any 'bargain-hunting' critiques by prospective buyers) .
Quite often , but not always , unknown/unseen details (both 'good & bad') will be revealed during & after disassembly of framing elements .
